Hi, My 94 accord ex had some exhaust leaks after the resonator. Just recently my car got wayy louder and it also has a very hard time accelerating past 25 MPH if I try and accelerate even more it sounds like it's misfiring. I jacked up my car and saw that right behind were the header meets with the cat converter was completely broken off(about 4 inches after the oxygen sensor). I had no warning lights on the dash, but I read the codes anyways using the paper clip method and it came up with code 43. I searched here and found code 43 was for fuel system, but also found that it can mean O2 sensor.
Also there is only one 02 sensor right?
Would the 02 sensor cause it not to go above 25mph?
Do you guys know of a cheaper place to buy all the pipes other than TAS website?

Well any help is appreciated thanks in advance.
